Solution – Alternative Approaches

Use suma to download missing prerequisites or apply a service pack ISO directly.

Verification & Acceptance Criteria

lslpp shows the new filesets at COMMITTED state and lppchk passes.

lslpp -L | head
lppchk -v
oslevel -s

Rollback Plan

Reject the applied filesets if the system becomes unstable.

installp -r -e /tmp/inst.log all
oslevel -s
lppchk -v

Prevention & Hardening

Use NIM lpp_source resources and SUMA to keep media complete and current.
